I need help solving this problem on Picoctf. The question is What happens if you have a small exponent? There is a twist though, we padded the plaintext so that (M ** e) is just barely larger than N. Let's decrypt this: ciphertext. The ciphertext is this. I tried using stack flow and the rsatool on GitHub but nothing seems to work. Do you guys have any idea of what I can do. I need to solve this problem asap

Explanation:

Explanation:

RSA encryption is performed by calculating C=M^e(mod n).

However, if n is much larger than e (as is the case here), and if the message is not too long (i.e. small M), then M^e(mod n) == M^e and therefore M can be found by calculating the e-th root of C.
